California’s SB 343 makes it illegal to put a chasing arrows symbol, a “please recycle” statement, or any similar recyclability claim on a product or its packaging sold in California unless the material is actually collected and sorted by recycling programs serving most of the state. The California SB 343 recycling label rules take full effect on October 4, 2026, apply to every brand selling into California regardless of size, and treat non-compliant labels as deceptive advertising under existing consumer protection law.
When the Rules Take Effect
SB 343 was signed in 2021, but the labeling restrictions only kick in 18 months after CalRecycle publishes its Material Characterization Study. That study was finalized on April 4, 2025, which sets the compliance deadline at October 4, 2026.1CalRecycle. SB 343 Material Characterization Study Final Findings There is no phased rollout and no grace period. Products sitting on California shelves after that date must already comply.
What Counts as Recyclable Under the Law
A product or package can only be labeled recyclable if the material clears two separate thresholds, both measured against what actually happens in California’s recycling infrastructure rather than what the material could theoretically do.2California Legislative Information. California Public Resources Code PRC 42355.51
- The material is collected for recycling by programs serving jurisdictions that together cover at least 60 percent of California’s population.
- The material is sorted into defined recycling streams by large-volume processing facilities that together serve at least 60 percent of recycling programs statewide.
Meeting both thresholds still isn’t enough on its own. The material also has to routinely become feedstock for new products or packaging. Something that gets collected and sorted but ends up in a landfill because no one buys the sorted output still fails the test. The law also accounts for a product’s shape and design, because certain forms jam or contaminate the automated equipment at recovery facilities even when the underlying material qualifies.
Materials That Now Fail the Test
CalRecycle’s study measures which materials are actually collected curbside and effectively sorted at processing facilities. Materials that scored zero percent for effective sorting include polystyrene foam packaging, polystyrene food service ware, PVC containers, compostable plastic bags, most plastic films, molded paper fiber, and composite food service packaging.1CalRecycle. SB 343 Material Characterization Study Final Findings Putting a recycling symbol on packaging made from any of these after October 2026 will almost certainly be treated as deceptive.
The list will shift as recycling infrastructure changes. CalRecycle must update the study every five years and can publish supplemental data between cycles.2California Legislative Information. California Public Resources Code PRC 42355.51
What Cannot Appear on Packaging
Any chasing arrows symbol, similar graphic, or statement telling the consumer to recycle the item is presumed to be deceptive unless the material meets the recyclability criteria.2California Legislative Information. California Public Resources Code PRC 42355.51 The presumption is legal, not rhetorical: it shifts the burden onto the manufacturer to prove the claim is accurate. Text claims like “please recycle” or “100% recyclable” are treated identically to the symbol. A material that can technically be recycled in a specialized facility somewhere cannot carry these claims if California’s mainstream infrastructure does not process it.
Resin Identification Codes on Plastics
The numbered resin identification codes on plastics (the 1 through 7 system) create their own compliance problem. Under Public Resources Code Section 18015, the resin code number cannot sit inside a chasing arrows symbol unless that specific plastic meets the statewide recyclability criteria.3California Legislative Information. California Code PRC 18015 Manufacturers who need to display a resin code without making a recyclability claim have to use a solid equilateral triangle instead. Because at least 29 other states require the chasing arrows around the resin code, national brands may need California-specific packaging.
Following the FTC Green Guides Is Not a Defense
Under California’s general environmental marketing statute, Business and Professions Code Section 17580.5, companies can normally defend green claims by showing they followed the Federal Trade Commission’s Green Guides. SB 343 explicitly removes that defense for recyclability claims.4California Legislative Information. California Business and Professions Code BPC 17580.5 A label that complies with the FTC’s “substantial majority” standard but fails California’s 60 percent criteria is still a violation.
Proving Your Own Claim
No state agency reviews or pre-approves recycling labels. Each brand evaluates its own packaging against CalRecycle’s published data and decides whether a recyclability claim is defensible.5CalRecycle. Accurate Recycling Labels Under Business and Professions Code Section 17508, the Attorney General, any district attorney, county counsel, or city attorney can demand that a company produce the evidence supporting its advertising claims.6California Legislative Information. California Business and Professions Code BPC 17508 A company that cannot produce documentation faces a legal presumption that the labeling is deceptive.
In practice, a defensible file needs three things: the material composition of the packaging, how that composition maps to CalRecycle’s characterization data, and evidence that the material type and form clears both the 60 percent collection and 60 percent sorting thresholds. Coordinating with packaging suppliers and tracking CalRecycle updates is the only way to build that record before a claim is challenged.
Penalties for a Non-Compliant Label
SB 343 does not create its own penalty provision. Violations are prosecuted under California’s existing false advertising and unfair competition statutes. Under Business and Professions Code Section 17536, each violation of the false advertising chapter carries a civil penalty of up to $2,500.7California Legislative Information. California Business and Professions Code BPC 17536 Because each non-compliant product unit can count as a separate violation, exposure for a widely distributed product adds up quickly. Section 17500 also classifies false advertising as a misdemeanor punishable by up to six months in jail, a fine of up to $2,500, or both.8California Legislative Information. California Business and Professions Code BPC 17500
Courts can also order immediate removal of non-compliant products from shelves. Under the Unfair Competition Law at Business and Professions Code Section 17200, an SB 343 violation can serve as the underlying unlawful conduct for a broader action seeking restitution and injunctive relief.
Can Consumers Sue Directly?
SB 343 does not give consumers a private right of action, so a shopper cannot sue a company directly for breaking SB 343’s labeling rules. Non-compliant labels can still trigger private litigation through other statutes. The Consumer Legal Remedies Act, at Civil Code Section 1750 and following, prohibits misrepresenting the certification or approval status of goods. The Unfair Competition Law lets private parties challenge any business practice that violates a separate statute. An SB 343 violation can supply the factual basis for either type of claim.
No Small Business Exemptions
SB 343 contains no exemptions based on company size, product category, or annual revenue. A small business selling a single product in California carries the same obligations as a multinational. The law reaches anyone who offers for sale, sells, distributes, or imports into the state any product or packaging bearing a recyclability claim.2California Legislative Information. California Public Resources Code PRC 42355.51
The Pending Federal Lawsuit
In March 2026, a coalition including the California League of Food Producers, the American Forest and Paper Association, and the Flexible Packaging Association filed suit in the U.S. District Court for the Southern District of California. The case, California League of Food Producers v. Bonta, argues that SB 343’s labeling restrictions violate the First and Fourteenth Amendments by compelling or restricting commercial speech. The plaintiffs target both the Section 42355.51 chasing arrows restrictions and the Section 18015 resin code requirements.
The suit could reshape or invalidate parts of the law, but it has not stopped the clock. The October 2026 deadline remains in effect, and companies that hold off on relabeling in hopes of a favorable ruling carry the full penalty exposure if the law survives.
